Submarine operation in the littorals is characterized by high shipping density, technologically current threats, and often limited maneuverability. The development of new acoustic countermeasure technologies is fundamental to survival in this environment. Modifications to the External Countermeasure Launchers (ECL) to support launch of multiple, highly capable 3” devices necessitates an aggres ...

Aurora Flight Sciences and the MIT Aero-Astro Department have been jointly developing the human interfaces and underlying automation for a planning system that enables a field operator to command a team of UAVs to perform operations consistent with expeditionary missions. During Phase II, these tools will be further developed and demonstrated as a comprehensive system including high-level collabo ...

Cornerstone Research Group, Inc. (CRG) proposes to fully develop polyurea coatings for blast and impact resistance. Polyurea coatings show promise for increasing the blast and impact resistance of buildings and vehicles, but further development is necessary to ensure the success of these materials. Currently, there is no method for assessing the suitability of a coating for blast and impact resist ...

The Marine Corps Expeditionary Fighting Vehicle (EFV) represents the next generation of armored and tracked troop carriers designed to operate over harsh terrain and in extreme environments. The protection of troop personnel on board the EFV is of paramount importance and recent developments in spray-applied polyurea materials have shown the potential to significantly increase blast protection to ...

The objective of this Phase I STTR program is to develop innovative lightweight (density < 1.17 g/cm3) polyureasiloxane hybrid coatings as multi-mechanism blast, fragmentation and environmental protective coatings for the Marine Corps Expeditionary Fighting Vehicle. NanoSonic will synergistically combine the impact resistance and mechanical durability of its existing hybrid polyureasiloxane copol ...

Navy and commercial divers are subjected to extreme environmental conditions which can compromise physiological and/or cognitive state. Divers are at risk of various health complications which can ultimately lead to death including barotraumas, hypo/hyperthermia, nitrogen narcosis, oxygen toxicity, decompression sickness, arterial gas embolism, and high pressure nervous syndrome. Even if the div ...

Current directed infrared countermeasure (DIRCM) systems integrate a mid-infrared laser with a pointer-tracker (P/T) head as a mated pair, comprising a single replaceable unit. The P/T head directs the laser power to the approaching threats: surface-launched and air-launched infrared-guided missiles. The protection of tactical aircrafts from infrared-guided threats requires separate DIRCM systems ...

This proposal aims at the development of a low-power deicing system using the newly developed magnetostrictive alloy as functional materials, namely the Ni-Mn-Ga alloy. Present studies have shown that the Ni-Mn-Ga smart alloy does not require excessive input power to operate while an impulsive strain of over 5% can be generated under a load of over 1 Mpa. When power is applied to the solenoid arou ...

The computational grid generation process remains a troublesome bottleneck in development of aerodynamic databases for complex geometries and multi-body configurations. The ability of Cartesian-grid based methods to perform automatic mesh generation and dynamic mesh adaptation allows for substantially reduced manpower, time and cost. The advantages of octree-based Cartesian-mesh methods have been ...

This Small Business Technology Transfer Research (STTR) Phase I proposal from Materials and Systems Research, Inc. (MSRI) and University of Utah (research institution) seeks to fabricate single-phase, polycrystalline KZr2P3O12 (KZP) and Al2-x(HfMg)x(WO4)3 ceramics with densities greater than 99.95% and a mean grain size of 1 ƒÝm. These ceramics have been chosen because of their low thermal expan ...
